Specification of Letters Patent.

Patented Nov. 6, 191 7.

Application filed Ma ch 8, 16, Ser No. 81,911.

To all whom it may concern:

Be it known that I, OsoAR A. FREEMAN, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Car-Stakes, of which the following is a specification.

This invention relates to car stakes, and more particularly to a stake that can be quickly and efiiciently brought into use, but when there is no use for the same, it can be efiiciently removed from its position attained when in use.

A still further object of this invention is to provide a car stake as described above that comprises essentially a plurality of horizontally secured sections that are prevented from movement outwardly relative to the car when the same are positioned for use, and can when not in use be quickly brought under the floor of the car and thus be out of the way and prevented from any unnecessary uses.

A still further object of this invention is the production of a device of the kind above described that is simple in construction, eiiicient in operation and consists of the minimum number of parts.

With these and other objects in view, this invention consists of certain novel construction, combinations, and arrangement of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings Figure 1 is a view in elevation of the end of a flat car showing my improved device mounted thereon and in use;

Fig. 2 is an inverted plan view of a portion of a flat car with my improved device mounted thereon;

Fig. 3 is a detailed perspective view of a pair of the improved sections that comprise this car stake;

Fig. 4 is a detailed perspective view of the trackway carried by the car adapted for the reception of the sections when the same are not in use;

Fig. 5 is a section taken on line 55 of Fig. 2;

Fig. 6 is a section taken on line 66 of Fig. 5.

Referring; to the parts by reference numerals, I have shown this device attached to an ordinary fiat car having a floor 10 and secured to the under surface of the floor by the angularly extending brackets 11 are trough-like trackways 12-, one end of the same being curved upwardly as at 13 and brought up in alinement with the upper face of the car floor 10, the end thereof in proximity with the upper face of the car floor being rigidly secured to the same by means of'the brackets 1% that are secured by the fasteners 15. As is clearly shown in Fig. a the trough-like trackways 12 are provided with a pluralityv of drain openings 16 and each of the same is provided with a gear receiving opening 17. Ribs 18 are formed on the upper face of the bottom of the trouglrlike trackway so as to reduce the friction caused by the movement of the stake sections on the same, to the minimum.

The stake proper comprises a plurality of blocks or sections 19 having one face thereof smooth and the other face provided with teeth 20, the said sections being pivoted together by means of the .links '21 which are secured to the sectionsby the pins 2-2 that pass through the links adjacent their ends and into the blocks. 'The sections 19 are cut away adjacent their end as at .Z'Sso that when the same are guided to the curved portion 13 of the trough-like trackways 12, they will be capable of a slight movement 1nwa-rdly relative to the car and thus prevent binding of the same as they make the curve before described. I

Operating means is provided for the sec-. tions or blocks 19 and a description of the same will now ensue. Bods 24 are carried by suitable bearings which are secured to the under surface of the car floor 10 adjacent the side edges thereof, the said rods extending longitudinally of the car floor and protrude beyond the end of the same the said end having fixedly secured thereto the wheel 25 or any suitable operating means 25. As is clearly shown in Fig. 2 the block sections 19 are positioned in the trough-like trackways 12 in such a manner as to present the toothed surfaces downwardly and therefore the rods 22 that are positioned beneath the trackways and adjacent the same have keyed thereto elongated pinions 26 that enter the trackways by means of the opening 17 before described. As is obvious movement of the wheel 25 will rotate the pinions 26 and by means of its engagement with the,

blocks or sections 19 move the stake made up of the sections in the desired direction. Each of the rods have secured to the protruding ends thereof ratchet wheels 27 and pivotally secured to one of the brackets that carry the bearing for the rods 24: is a pawl 28 that by gravity engages the said ratchet wheel 27. By this arrangement of the rods the rotation thereof in one direction is prevented and therefore the car stakes can only be moved in one direction unless the pawls 28 are moved out of engagement with the ratchet wheel 27.

It will be seen from the foregoing description that the blocks or sections 19 forming the car stake are normally retained in the trough-like trackways 12 beneath the car floor and thus shielded from the weather. However when the car is being loaded and it is wished to provide the same with stakes the rod 24 is rotated by means of the wheel or similar operating means 25 and the blocks or sections are moved upwardly beyond the upper face of the floor of the car and the pressure exerted by the load on the floor of the car, that will necessarily engage the blocks will prevent the same from falling inwardly or collapsing. However as is clearly shown in Fig. 1 the sections or blocks will form a resistance against outward pressure relative to the car in that the same are so formed and so connected that they are only capable of collapsing inwardly relative to the car. After the stake has reached the desired height the same cannot inadvertently move back into the trackway in that the pawls 28 are in engagement with the ratchet wheels 27 and thus the elongated pinions are immovable in one direction which because of the engagement of the pinion with the sections 19 prevents the sections from moving in the trackways.

It is obvious that minor changes may be made in the form and construction of this invention without departing from the material parts thereof. It is therefore not wished to confine the invention to the exact form herein shown and described, but it is wished to include all such as properly come within the scope claimed.

What is claimed is:

1. In combination with a support, of a stake therefor, comprising a plurality of Copies of this patent may be obtained for five cents each,

ti ons, a trackway sections hingedly secured together, means for moving said sections to operative and inoperative positions relative to said support and means whereby said sections are capable of movement inwardly of said support but prevented from moving outwardly relative to said support.

2. In combination with a support, of a stake therefor comprising a plurality of collapsible sections, a trackway carried by said support adapted to receive said sections and means for engaging said sections while the same are in said trackway to impart movement thereto.

3. In combination with a support, of a stake therefor comprising a plurality of sections, a trough-like trackway carried 011 the underface of said support and means on said support for imparting movement to said sections, whereby the same may be moved upwardly, project partly above said support or moved wholly into said trackway beneath said support.

4.. In combination with a support, of a stake therefor comprising a plurality of sections, a trackway carried by said support adapted to receive said sections, each of said sections having a toothed face, a pinion rotatably carried by said support and engaging the toothed faces of said sections when the same are in said trackway and means for operating said pinion whereby movement is imparted to said sections.

In combination with a support, of a stake therefor comprising a plurality of secfor said sections, means for engaging said sections to impart movement thereto and means in engagement with said first mentioned means to prevent move ment of the same in one direction and thus retain said stake sections in an operative position. I

In testimony whereof I affix presence of two witnesses.
